Abstract

Ammunitionm housing (1) has a cover pt. (2) consisting of a disc-shaped closure (3) with a stirrup (4) and a threaded pt. (5) with internal (6) and external (7) threads. A support element (11) is screwed on to the external thread and itself has an external thread (19) on which a nut (20) is screwed, supporting a plate insert (14). The support element can be adjusted on the external thread, according to the shape of the plate.

Description

The invention relates to an ammunition housing with a him fixed lid part, which inside the Ammunition housing has an external thread on which a Support element is screwed, which an installation part one side supports.

Such an ammunition housing is in the DE-GM 87 12 400 described. By means of the support element is a built-in part (receiving body) on the cover part fixed. This definition presupposes that on Cover part for the side of the support element facing away from the Installation part is a stop in the correct position. If the built-in part is a circuit board, then it cannot can be assumed because the board is case by case can have different curvatures and their Fixing the cover part alone is not sufficient to To absorb loads that accelerate the Ammunition housing in one direction and in the opposite direction occur like this for example when shooting the ammunition housing in a beam and when it is ejected from the Carrier floor is the case.

The object of the invention is to provide an ammunition housing to propose at the beginning, in which by means of Cover part of a board in its central area in both Directions is supported, the support to the Shape of each board is customizable.

According to the invention, the above task is for one  Ammunition housing of the type mentioned above solved that the support element has an external thread, on which a nut is screwed, that of a Board-formed mounting part on its other side supports, and that the support element depending on the shape the board is adjustable on the external thread.

The support element forms an adjustable one Stop for the board. The support element is each set so that the board despite one more or less strong curvature rests on the support element. By means of the set support element screwed nut the board to the Support element pressed. This makes the board in both Directions are supported securely so that they are in the occurring loads, especially the Do not break the firing load and the discharge load or can deform in such a way that they are intended for it can break electrical conductors.

The support element preferably has on its circumference a collar on which an edge of a recess of the PCB is pressed by means of the nut. On hers The outer circumference is the board by means of a screw ring in the Ammunition case held.

Further advantageous embodiments of the invention result from the subclaims and the following Description of an embodiment. In the drawing demonstrate:

Fig. 1 shows a partial longitudinal section of an ammunition housing and

FIG. 2 is a partial view of area II, enlarged compared to FIG. 1.

Of an ammunition case (1), a lid part (2) is fixed. This consists of a disc-shaped end body ( 3 ), a bracket ( 4 ) and a threaded part ( 5 ). The closing body ( 3 ) is fastened in the ammunition housing ( 1 ). The threaded part ( 5 ) is formed on the side of the bracket ( 4 ) facing away from the closing body ( 3 ).

The threaded part ( 5 ) has an internal thread ( 6 ) and an external thread ( 7 ). A safety device ( 8 ) is arranged between the closing body ( 3 ) and the threaded part ( 5 ), encompassed by the bracket ( 4 ). A clamping screw ( 9 ) is screwed into the internal thread ( 6 ). This presses on a tensioning disk ( 10 ) inserted between the securing device ( 8 ) and the tensioning screw ( 9 ). The securing device ( 8 ) is fixed to the cover part ( 2 ) by tightening the clamping screw ( 9 ) in the internal thread ( 6 ).

A support element ( 11 ) is screwed onto the external thread ( 7 ) of the threaded part ( 5 ). For this purpose, this has an internal thread ( 12 ). A circumferential collar ( 13 ) is formed on the support element ( 11 ).

A circuit board ( 14 ) is provided with a recess ( 15 ) which forms an edge ( 16 ). On its outer circumference ( 17 ), the board ( 14 ) is held in the ammunition housing ( 1 ) by means of a screw ring ( 18 ).

The support element ( 11 ) has an external thread ( 19 ) onto which a nut ( 20 ) can be screwed. The support element ( 11 ) is provided with points of attack ( 21 ) on its side facing away from the end body ( 3 ). The support element ( 11 ) can be rotated on these by means of a tool and thus adjusted in the longitudinal direction of the threaded part ( 5 ).

The recess ( 15 ) of the board ( 14 ) is placed over the support element ( 11 ) so that the edge ( 16 ) rests on the collar ( 13 ) of the support element ( 11 ). The edge ( 16 ) is pressed onto the collar ( 13 ) by means of the nut ( 20 ).

The function of the described device is approximately as follows: If the circuit board ( 14 ) is fixed in the ammunition housing ( 1 ) by means of the screw ring ( 18 ), then it will be more or less curved in its central area, at its edge ( 16 ). The support element ( 11 ) is then adjusted so that its collar ( 13 ) rests freely on the edge ( 16 ). The nut ( 20 ) is then screwed onto the external thread ( 19 ) so that the edge ( 16 ) is firmly clamped between the nut ( 20 ) and the collar ( 13 ).

A shot load acting in direction (A) on the central area of the board ( 14 ) takes up the nut ( 20 ) and transmits it to the support element ( 11 ), which in turn forwards it to the end body ( 3 ) defined in the ammunition housing ( 1 ).

The collar ( 13 ) of the support element ( 11 ) absorbs an ejection load acting in the direction (B) on the central region of the board ( 14 ). This in turn transfers them to the final body ( 3 ). The board ( 14 ) is thereby securely supported in both directions even with the inevitable tolerances.
